The assumption is that patients can and will read this document to educate themselves about their TKR surgery. The interactive e-learning patient education intervention extends beyond simple accessibility to information and includes interactive features. The intervention spans surgery and rehabilitation aftercare with patients undergoing TKR. Measurements will take place at pre-admission before any preoperative education takes place and at 6 weeks, 3 months and 1 year after TKR surgery. Patients will have the option of completing questionnaires online using Empower or hard copy sent by mail. They will also receive reminders by email or phone about completing the questionnaires.
